The EDCO DS-18 is an 18-inch electric walk-behind saw built for contractors who need clean, controlled cuts in concrete and asphalt without the exhaust fumes of a gas engine. Its 5 HP electric motor makes it a go-to machine for indoor and enclosed work - parking decks, warehouses, basements, and food or healthcare facilities - where running a gas saw is not an option. A heavy 7-gauge laser-cut steel frame and anti-vibration engine mount keep cuts straight and reduce operator fatigue over a long day.
Where the DS-18 fits best
This saw is sized for serious flatwork rather than occasional homeowner use. Crews reach for it to:
- Cut control and expansion joints in fresh and cured concrete slabs.
- Work indoors and in poorly ventilated spaces where a gas saw's exhaust is a safety hazard.
- Saw asphalt and concrete for repairs, trenching layout, and demolition prep.
- Handle decorative and finish cuts where its downcut blade rotation leaves a cleaner edge and a clearer view of the line.
Large screw-type depth controls let the operator dial in an exact cutting depth, and wide-T handles with rubber grips plus solid-steel lifting handles make it easy to position and transport.

Frequently asked questions
Is the EDCO DS-18 gas or electric?
It is electric, powered by a 5 HP single-phase motor on 230V at about 19.5 amps. Because there is no engine exhaust, it is well suited to indoor and enclosed cutting where a gas saw would create dangerous fumes.
How deep does the DS-18 cut?
It accepts an 18-inch blade and cuts to a maximum depth of 6.75 inches in a single pass, enough for most concrete flatwork, control joints, and asphalt cutting.
Does the saw come with a blade?
No. The blade is sold separately so you can match the diamond blade to your material - concrete, cured concrete, asphalt, or green concrete each cut best with a different bond.
Is it a downcut or upcut saw?
The DS-18 is a downcut saw. Downcut rotation pulls debris down and forward, giving the operator a clearer view of the cut line and a cleaner edge, which is why it is popular for finish and decorative work.
What power supply do I need on the job site?
A 230V single-phase circuit rated for roughly 20 amps. EDCO specifies a maximum extension cord length of 100 feet using 10-gauge cord to avoid voltage drop that can damage the motor.
